| What wintering squirrels can teach astronauts Posted: 27 Jan 2022 11:15 AM PST The unique way that ground squirrels burn almost no energy when they hibernate -- with no loss of muscle mass -- has implications for space travel, biologists find. |
| Scientists explain mysterious finger-like features in solar flares Posted: 27 Jan 2022 08:43 AM PST Astronomers have presented a new explanation for the mysterious downward-moving dark voids seen in some solar flares. |
| Scientists make a new type of optical device using alumina Posted: 27 Jan 2022 07:39 AM PST Researchers have developed an alumina short-wavelength absorber patterned with moth eye-like structures. These new anti-reflective structures will improve the performance of telescopes studying radiation from the Big Bang. |
| Ancient ice reveals mysterious solar storm Posted: 26 Jan 2022 11:42 AM PST Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events. |
| Mysterious object unlike anything astronomers have seen before Posted: 26 Jan 2022 09:24 AM PST A team mapping radio waves in the universe has discovered something unusual that releases a giant burst of energy three times an hour, and it's unlike anything astronomers have seen before. Spinning around in space, the strange object sends out a beam of radiation that crosses our line of sight, and for a minute in every twenty, is one of the brightest radio sources in the sky. |
